Chickens with average mass of 2.0 kg and average specific heat of 3.55 kJ/kg:C are to be cooled by chilled water that enters a continuous flow type immersion chiller at 0.5 C. Chickens are dropped into the chiller at a uniform temperature of 15 C at a rate of 500 chickens per hour and are cooled to an average temperature of 3 C before they are taken out. The chiller gains heat from the surroundings at a rate of 200 kJ/hr. a ? + Using the above equations as starting points, determine: (a) Any valid assumption. (b) determine the rate of heat removal from the chickens, and (c) determine the mass flow rate of water, if the temperature rise of the water should not exceed 4 C. y2 0-W = Scy e pdv + Sos (n + "* + gz) p V Scs (n + v + gz) p V .d where e = u + v + gz
